ADJUSTABLE STOP-BEAD FASTENER.

SPECIFICATION forming part of Letters Patent No. 787,596, dated April 18, 1905.

Application filed June 11, 1904; Serial No. 212,210. i

To all whom it may concern.-

Be it known that I, VVAsHINGTON VAN GAAs- BEER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Adjustable Stop-Bead Fasteners, of which the following is a specification.

This invention relates to an adjustable stopbead fastener for window-frames, the object being to provide a new and improved means for securing the stop-beads in such manner that they may be accurately adjusted to bear on a window-sash with suflicient friction to prevent rattling of the windows and at the same time permit the sash to be easily raised and lowered.

A further object of the invention resides in the easy and quick removal and readjustment of the stop-bead without marring it or the window-frame when it becomes necessary to record, paint, glaze, or repair in any way a window-sash when its removal from the window-frame is necessary or desirable.

My invention is also of value in certain forms of swinging windows, wherein it is necessary to remove the stop-bead before the sash can be swung.

The ease and rapidity with which a stopbead can be removed when fitted with my invention renders it valuable when applied to swinging windows of the kind above mentioned.

In the accompanying drawings, Figure 1 is a horizontal sectional View of part of a window-frame with my invention applied thereto. Figs. 2, 3, and 4 are detail views of the several parts. v

The window-frame (indicated by 1) is provided with the usual stop-bead 2 for holding in place against the parting-bead 3 the lower sash of a window.

\(Vhen stop-beads are fastened to windowframes by nails and screws, the general result is unsatisfactory, as it is a well-known fact that in dry weather or when the parts are worn by use the sash becomes loose and rattles in the window-frame to such an extent as to be very annoying, while 'at other times the windows stick in their ways owing to the expansion due to dampness and are raised with difdriver.

ficulty. To overcome these and other objections, 1 have devised an adjustable fastening for stop-beads, (illustrated in the drawings) by means of which the stop-bead can be quickly and accurately set to bear with sufficient firmness against the windows to prevent their shaking and at the same time permit them to be raised and lowered with ease.

To accomplish the results above mentioned, I secure by screws to that part of the win- (low-frame covered by each stop-bead 2a suitable number .of plates or disks 4, countersunk in the window-frame, as shown, each of which plates is centrally and horizontally slotted at 5, one end 6 of said slot being enlarged, as seen in Fig. 4. Within the stop-bead 2, axially of each plate or disk t, is fastened a nut 7, in which is threaded a preferably lefthanded screw 8, the outer end of which is nicked or slotted for the point of a screw- The inner end of said screw 8 has a reduced neck 9, carrying thereon a head 10, adapted topass through the enlargement 6 of the slot 5, with which slot the neck 9 is normally engaged. The nut 7 is for the greater part of horizontal or polygonal form externally, its inner end 11 being of frusto-conical form.

The preferred form of setting the nuts 7 in the stop-bead 2 is by first boring through said stop-bead a hole for each nut of slightlyless diameter than the flats of said nut, then placing the frusto-conical end 11 of said nut in the hole and driving the nut home-that is to say, until its outer end becomes flush with the face of the stop-bead. By this means the nut is caused to tit tightly in the stop-bead and be prevented from turning therein by the polygonal form of the nut. The frusto-conical or tapered end of the nut being of less diameter than its outer portion, the nut cannot be drawn through the stop-bead when pressure is applied to the screw 8 for tightening it. The conical end of the nut also serves as a guide for the nut while being driven in place. By the use of my invention but one size is required, for although stopbeads are made in various sizessay from onequarter to three-quarters of an inch thick-- the nut and screw which are made for the thinnest head are sufficiently long for the thickest size.

Other devices of this class, in so far as I am aware, are less simple in construction and more diflicult to apply, as careful measurements and accurate work are necessary to fit them to windows. My invention, on the contrary, which consists of but three pieces, requires neither skill nor accuracy to apply. It is only necessary to place a stop-bead in position and drive an awl or other suitable tool through it and into the window-frame at the places where the devices are to be attached, thus obtaining at one operation the center for a nut 7 and a plate 4. After boring the countersink for the plate 4 a portion of the window-frame is cut away, as at 12, for the head 10 of the screw to move laterally. Should the nuts be first placed in the stop-bead, the centers for the countersink are quickly and accurately obtained by turning the screws 8, after fitting the stop-bead, until the points 13 on the heads 10 penetrate the window-frame.

After the several parts have been placed in position the heads 10 are inserted in the enlargement 6 and the stop-bead pushed toward the sash (the necks passing into the slots 5) until it bears thereon with sufiicient pressure. The screws are then turned, and their heads bind on the plate 4, thereby holding the stopbead in fixed position. I prefer to make the screws with a left-hand thread, as the natural tendency when tightening a screw is to turn it to the right, and as the screw must move endwise to tighten the stop-bead, if the thread be a right-hand one, the parts will loosen instead of tighten when turned to the right.

Having thus described the invention, what is claimed as new is A window-bead fastener comprising a slotted plate, adapted to be fixed to a windowframe, a polygonal nutadapted to be driven into a stop-bead, and a screw fitted to said nut having a head and a reduced neck, the latter adapted to slide in the slot in the aforesaid plate.

In testimony whereof I affiX my signature in presence of two witnesses.
